THE ROOM

Molly and Jason Mesnick, who met on season 13 of ABC's The Bachelor and wed in February 2010, welcomed daughter Riley Ann in March – but began preparing her room long before her arrival. "We started when Molly was about four months pregnant, and finished two weeks before she was due," interior designer and fellow former Bachelor star Jillian Harris tells PEOPLE. "The inspiration came from Molly, and the fact that she didn't know if she was having a boy or girl. She's a very classic person, and wanted the room to be neutral and fresh."
